Patent number: 6458449Abstract: An ink jet printable coating for holographic paper is presented. The coating utilizes a high dyne primer layer and a secondary layer. The secondary layer includes a plurality of microscopic pores which are preferably 1 to 6 microns in diameter. The pores are sized to allow ink jet ink to penetrate during the printing process. The coating is compatible to both water based and solvent based inks. The pores serve to provide a site to which the ink jet ink can anchor and set, thus preventing the ink from running when initially applied to the surface and speeding the rate of ink drying. Additionally, the secondary layer is porous enough to absorb the ink as it dries. The deeper the secondary layer, the further to ink can penetrate for greater adhesion to the surface and for faster drying.Type: GrantFiled: September 15, 1999Date of Patent: October 1, 2002Assignee: Hazen Paper CompanyInventors: Kyle R. Parent, Timothy R. McDonald, Earl C. Spice, John H. Hazen

Patent number: 6395375Abstract: When a temporary adhesive layer for peelably bonding a transfer-receiving material to a thermal transfer sheet comprising a substrate film and a heat-fusible ink layer disposed on one side thereof is caused to comprise a specific adhesive, an excellent composite thermal transfer material is provided. In such a composite thermal transfer sheet, the thermal transfer sheet is firmly bonded to the transfer-receiving material so as not to cause wrinkles or deviation, both of these members may easily be peeled from each other so that the ink layer is exactly transferred to the paper in a transfer region and it is not transferred thereto at all in a non-transfer region, whereby the transfer-receiving material is not contaminated. An antistatic treatment provides a composite thermal transfer sheet causing no trouble due to charging at the time of or after printing operation.Type: GrantFiled: November 20, 1998Date of Patent: May 28, 2002Assignee: Dai Nippon Insatsu Kabushiki KaishaInventors: Hirokatsu Imamura, Koichi Nakamura, Hirokazu Kaneko
